Apply fire-flow constraints only to nodes upstream of the hydrant in Hydrant Testing run

When running a Hydrant Testing run, there are only options to apply constraints globally or to the Fire Zone of the hydrant being testing. If the constraint node is downstream of the hydrant being tested it is likely that the reported hydrant flow is underestimated as in reality a fully-open hydrant will be able to draw additional water. As such, could there be a feature to only apply constraints to the nodes upstream of the hydrant tested. A workaround currently would be to apply exceptional flow to an individual hydrant and use the upstream trace to create a "fire zone" that constraints can be applied to however this is not a feasible workflow for a large set of hydrants.
